I'm fairly new to geocaching and have been using my iphone 3gs, which works fairly well in my urban environment.
The GPS accuracy leaves a bit to be desired, but I can usually sort it out by pulling up the google satellite map.
I'm ready to get a dedicated GPS for better accuracy (and I have been starting to hide caches with the help of my phone and then later, pegging the site on this site: http://itouchmap.com/latlong.html ), but have some questions:
1) what is a reasonably priced unit (under $200) with maps as clear as google?
2) (total newbie question) - I like the iphone because if I'm in a new spot unexpectedly, I can ask the phone "are there any caches around here?" and off I go. Can I do that with the GPS, or do I have to preload them with my computer before I go?
3) Finally, any recommended units that play well with a mac?
thanks!
